' ingl menno The chamber F and the detlector G are intended to heapplied tot-he vaporizing-chambowel whatever exterior forni that may be.

ln the forni of vnporlzing-chamber shown in Figs. l and 2 l have foundthat if it he made large enough fornse underatenmboilers,for

inetnn'ce, the iiaine passen up around the vaporizng-ohnmber and ontthrough the exterior tubes of the boiler, leaving the interior tnhonprnotioniiyfree of llame, or if the 4boiler orlotllcr vessel has notube, thon tite central portion of the bottom of the vessel ie notatroci: h); the llame. Narrow channels or passage-ways' throughthevaporizingchamber have been found wholly inadequate toproduce thedesirable uniform dietribntion oi' llame upon the bottom of tho vessellocated over the houter. Therefore I make' tite vaporiziugelnnnberwithfour or more radial wings, as shown in Fig. 3, extending from acommon central part and leaving open spaces, as at ll ll, between them.The

wings are hollow and constitute portions of `thevaporizi|\g-chninber,connuunicnting with the ventral portion of saidchamber. Ihe open spaces between the wings maybe made of greater onionsextent inproportion to the nl'ingn, according to the work required oftient. to paas up between them and near to` the conter of the burner,and the wings compel tho remaining portions to move fartherawny fromthoeenter before theyoan'reach the bottoni of the boiler or othervessel. This .construction also enables nio to reduce the `izo of thethune ns occasion may require without concentrating itagainstanypurtictr lar point of the-bottom of theobjeet to be hunted. 'lhorudlatiugwlngs are gradually widened from their inner to their outerends, nu indicated, so that nt their outer portions they afford moreroom for the .oxpnneion of vtheir contents than ntlthcir inner portions`and more exterior surface tobe heated. 'lhus when the llame is greatlyincreased the 'lhoy permit a portion of the limne roo inn-nor respondsin furnishing n eorrespond- 'lho improved burner may be mounted inconnection with the object tobe heated in any ninnw lenired.

lieing conntrneted and arranged eiibstantinlly iu accordance with theforegoing explanations the improvements have been found to answer nilthe purposes or objects of the invention hereinbel'ore alluded tofllnving now fully described my invention, what I eluiln un newlhereiu,and desire to eoeuro by Letters ln-tcnt, iii-- 1.- in n burner oi' theohnrnotor herein set forth, 'the' vapotiziug-chninber supplied with nnumborof interior partitioneA oeated tween the lult-t nntlmttletgnidvnporiningchamber being surmounted by asecond chamn ber communicatingwith the interior of the vaporizing-chamber and affording a free passagefor gas or vapor above the partitions and above the top of thevaporizing-chamber, for the purposes set forth.

2. In a burner of the character herein set forth, the vaporizing-chambersupplied with common central portion, leaving open spaces between thesaid wings for passage of flame, the wings being gradually widened fromtheir inner to their outer ends, substantially as shown and for thepurposes set forth.

4E. In a burner of the character herein set forth, the combination withthe vaporizing-- chamber having radial wings projecting :from a commoncentral portion and leaving open spaces between the wings for thepassage of iame, of internal partitions extending into the wings,substantially in the manner and for the purposes set forth.

In testimony whereof I have signed my name to this specication in thepresence of two subscribing witnesses.
